Unlocking Ultra‐Long Cycle Stability of Li Metal Electrode by Separators Modified by Porous Red Phosphorus Nanosheets

open access: yesAdvanced Functional Materials, EarlyView.
Coating the standard polypropylene separator with a porous red phosphorous nanosheet greatly improves cycling performance in Li electrode cells. The phosphorus‐based surface chemistry deactivates electrolyte solvent decomposition and enhances the cleavage of F‐containing salt, resulting in an inorganic‐dominated electrolyte interphase (SEI) composition

Quantum interference probed by the thermovoltage in Sb-doped Bi2Se3 nanowires

open access: yesiScience, 2023
Summary: The magnetic-flux-dependent dispersions of sub-bands in topologically protected surface states of a topological insulator nanowire manifest as Aharonov–Bohm oscillations (ABOs) observed in conductance measurements, reflecting the Berry’s phase ...

Boosting Polysulfide Conversion on Fe‐Doped Nickel Diselenide Toward Robust Lithium–Sulfur Batteries

open access: yesAdvanced Functional Materials, EarlyView.
This work reports an advanced functional material based on Fe‐doped nickel diselenides toward robust lithium–sulfur batteries, demonstrating that Fe‐rich cores and surface doping enhance the density of states at the Fermi level and introduce unpaired electrons for the improvement of the LiPS adsorption and catalytic conversion. Abstract Sulfur offers a

Single Atom‐Particle Tandem Catalysis Enables Enhanced Desolvation Kinetics for Low‐Temperature Li‐S Batteries

open access: yesAdvanced Functional Materials, EarlyView.
In this work, the tandem catalyst consisted of single Fe atom and Fe3C nanoparticles on porous carbon sheet is initially proposed and developed to facilitate the dissociation of Li(solvent)x+ to release more isolated Li+ to participate in the subsequent polysulfide redox conversions by decreasing the related barriers, contributing to fast kinetics of ...

Fermi surface determination from momentum density projections

open access: yesNew Journal of Physics, 2016
The problem of determining a metal’s Fermi surface from measured projections of the electron or electron/positron momentum densities, such as those obtained by Compton scattering or angular correlation of positron annihilation radiation, respectively, is

Effects of Temperature Annealing on the Intrinsic Transport Mechanisms of Solution Processed Graphene Nanosheet Networks

open access: yesAdvanced Functional Materials, EarlyView.
Unravelling charge transport mechanisms in graphene nanosheet networks: by combining temperature‐dependent conductivity measurements with a Random Resistor Network model, this study identifies a transition from hopping‐dominated conduction to a band‐like transport mechanism.
